importing raw images

what version of iPhoto?

Your camera does not appear in the list of supported cameras see

OS X Mountain Lion: Supported digital camera RAW formats

If your camera is not in this list then OS X cannot decode the Raw files.

As Frank Caggiano said, your camera is not (yet) supported by iPhoto or Aperture. A later Digital Camera RAW Compatibility Update may include support for the camera. For the time being you could try several work-arounds.

• Use the raw developement software that came with your camera to convert the image files to a lossless format like tiff or PSD. The camera specific raw developement usually will give very good results, since the manufacturer knows the camera best.
• Or try, if Adobe's free DNG Converter can convert the raw files to a DNG version, that Aperture can recognize. Aüerture should recognize DNG files generated by the Adobe DNG Converter with the “Convert to Linear Image” option turned off. This way, your original files will remain raw files.

Another option - shoot raw+jpeg pairs for the time being, if your camera supports it, and work with the jpeg as original files, while you are waiting. In Aperture you can import the raw files later and switch to the raw as master files.
